hector: The HD transmitter you are referring to is already one of the second most powerful in the country, and so your problem is really being caused by the aerial system you are using and not in any way connected with the transmitter.

However, unfortunately its not really possible to be able to offer advice as far as remedial actions are concerned without having knowledge of your location, PLUS of course knowing where your present aerial is located? although "if" by any chance its a "same room as the TV" type then there isn't much that you can really do about it except to try moving it around whilst you are observing the quality being indicated on the screen.

Could you tell me the best indoor aerial to use . At the moment I use one with an ampierfiter . I can't spend anymore than £25 . Right now I'm getting TV from Yorkshire I think high pressure is here but I know as soon as high pressure has gone I will be with poor signal again . My aerial at the moment is a one for all aerial from Argos it cost £20 . Its very sensitive to moving the wire . So I want one that is the best you can get .

hector: Good morning.

Generally speaking indoor aerials are not suitable for Freeview reception. The system was designed for everyone to use a rooftop aerial. There is a small, old article on them here Indoor aerials | Installing | ukfree.tv - 11 years of independent, free digital TV advice

However, if you ARE going to spend a butget of £25 - you might find it better spent on putting the aerial you do have in a better position.

You can get 10 meters of decent aerial cable for a tenner. If you can move the aerial you do have to somewhere in the room (perhaps high up near a window) you *MAY* be able to get a more stable signal.

I cannot get any channels from Com7 HD from Sandy Heath. There is intermittent high signal level, but no signal quality from channel 32.
